L1
This document discusses the key concepts of physics and the scientific method. It explains that physics aims to understand nature's rules through studying phenomena like star patterns and weather. The scientific method involves making hypotheses, predicting consequences, experimenting, and finding rules. It provides examples of Aristotle's hypothesis about falling objects being disproven by Galileo's experiments. Theories are distinguished from hypotheses as being synthesized from many verified hypotheses. The document asks the reader to determine which of several examples constitute a scientific hypothesis. It also distinguishes science from technology, with science answering theoretical questions and technology applying scientific knowledge practically.
